Abstract

1. Safety device with construction machines, in which (a) at least one sensor (16 or 34) is provided, which responds to the ground surface approximately in the ground contact surface (14) of the construction machine (10), (b) the sensor (16 or 34) is adapted to trigger an error signal with a downward slope of the ground surface relative to the ground contact surface (14), characterized in that (c) the sensor (16 or 34) is a photoelectric sensor, and (d) the photoelectric sensor (16 and 34) has a V-shaped path of rays, in which a light source (44) is really imaged approximately in the ground contact surface (14) of the construction machine (10) through a first optical system (46) and the real image (52) is then imaged upon a photoelectric detector (60) through a second optical system (62), the axis (64) of which forms an angle with the axis (48) of the first optical system (46).
